Effect of driving frequency and power on droplet size atomized by a multimodal transducer.

ABSTRACT: Ultrasonic atomization is used in various applications such as medical devices, material synthesis, and humidity control. To meet the needs of different applications, the required droplet size ranges from a few microns to several hundred microns. In this study, we realized wideband multiple-frequency atomization with a multimodal transducer, which could control the size of atomized droplets by switching operating frequencies. A parabolic reflector served to focus the incident ultrasound waves, and a circular plate was employed to excite bending modes. By comparing the results of frequency response experiments with those of finite element simulation, nine different bending modes were acquired in the range of 500-2500 kHz. Then, 734, 949, 1530, and 2063 kHz were selected to examine atomizati
